The nation's expanding waistline has been well documented, though Wednesday's report is the first to quantify it based on how many pounds the average person is carrying.

In 1960-62, the average man weighed 166.3 pounds. By 1999-2002, the average had reached 191 pounds.

Similarly, the average woman's weight rose from 140.2 pounds to 164.3 pounds.

The report also documented a dramatic increase in weight when measured by body mass index, a scale that takes into account both height and weight. Average BMI has increased from about 25 to 28 over the 40-year span.

Anyone with a BMI of 25 and up is considered overweight, and those with BMIs of 30 and up are considered obese.

Americans are also getting a little bit taller.

Men's average height increased from 5 feet 8 inches in the early 1960s to 5 feet 9½ inches in 1999-2002.

The average height of a woman went from just over 5 feet 3 inches to 5 feet 4 inches.
